[logback-user] What is the log4j.properties file equivalent for logback?

Or, do I really have to do this: Logger logger = LoggerFactory.getLogger(MyAppWithConfigFile.class); LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory(); JoranConfigurator configurator = new JoranConfigurator(); configurator.setContext(lc); configurator.doConfigure(args[0]); Thanks, Michael
